Water quality treatment system and method

Abstract

The invention relates to the technical field of water treatment, and provides a water quality treatment system and a water quality treatment method. The system comprises a first wind power transmission mechanism and a biofilm water treatment system, wherein the biofilm water treatment system comprises a biofilter and an aeration component, the aeration component is driven by the first wind power transmission mechanism, an aeration quantity control component is arranged in the aeration component, and a water intake quantity control component and a water discharge quantity control component are arranged on the biofilter. According to the water quality treatment system and method, the aeration control component is utilized to control the air volume of the aeration component, and specifically comprises controlling the total aeration amount or the aeration flow rate of the aeration amount control component, and simultaneously eliminates the influence on the aeration intensity due to the wind power fluctuation as much as possible by combining the on-off control or the flow rate control of the water intake quantity control component and / or the water discharge quantity control component, thereby realizing that the oxygen supply and the pollution load in to be treated sewage in the biological filter are in a relatively balanced state, and the water quality of effluent always keeps stable and up to standard.

Description

technical field [0001] The present invention relates to the technical field of water treatment, and more specifically, to a water quality treatment system and method. Background technique [0002] The rural "toilet revolution" and the treatment of rural centralized and distributed sewage require energy-saving, simple, low-maintenance or maintenance-free sewage treatment systems. At present, as the main application of biological treatment technology to control water pollution, it mostly relies on electricity to supply power to motors to maintain the operation of water treatment equipment. However, for landscape water bodies and wild water bodies scattered in remote areas such as plateaus, mountains, and islands outside the urban agglomerations in eastern my country, the power supply lines required to build sewage treatment facilities are expensive and technically difficult; while fossil energy such as petroleum and coal is used to drive Motor operation and other methods consu...

AI Technical Summary

Problems solved by technology

[0005] The embodiment of the present invention provides a water quality treatment system and method, which solves or at least partly solves the problem in the existing water quality treatment system that the effluent water quality is not up to standard due to the variable wind force affecting the aeration intensity.
